RESILIENT HANPLE BAR FOR BICYCLES OR THE LIKE.

SPECIFICATION forming part of Letters Patent N 0. 786,857, dated April11, 1905.

To all whom, itmay concern.-

Be it known that I, MARTlN THIERFELDER, medical doctor, res'ding atZwickau, Saxony, Germany, have in ented new and useful Improvements inResilient Handle-Bars for Bicycles or the Like, of which the followingis a specification.

' The handlebars for bicycles, tricycles, and other vehicles have beenconnected with the fork of the front wheel by strong spiral springs inorder to avoid the jars of the wheel while riding over rough ground.These devices have the inconvenience that the rider looses the controlof his wheel on rough ground just where the resiliency is mostdesirable, because these springs yield also laterally and cannot preventaccidental turning of the wheel with the same efficiency as afork whichis rigidly connected with the handlebar.

The present invention is designed to obviate this inconvenience, and itis represented in the accompanying drawings, in which- Figure 1 showsthe new device in side elevation. Fig. 2 shows a modified form of thehandle. Figs. 3 and 4: are longitudinal sections through the handle andthe end of the handle-bar.

The handle-bar is made a little shorter than usual, according to thepresent invention, and

in the ends a a sleeve 6 is inserted, having a rectangular longitudinalperforation adapted to receive a flat spring 0, which is with one endsecured to the handle h, while the other end can freely slide in thelongitudinal hole of the sleeve Z) and can be adjusted therein and setfastby a set-screw 01.

Figs. 1 and 3 show that the handle is prospring 0V is pushed altogetherinside.

Application filed December 8, 1903. Serial No. I84,246.

vided with a tubular part adapted to slipover the end a of thehandle-bar, so that the latter can be used like a rigid handle-bar whenthe Figs.

2 and 4 show a modified arrangement for the same purpose, the handle 72,inclosing a solid part, to which the end of the spring cis screwed.The-said solid part can be moved into the end of the handle-bar.

Having thus described my invention, what I claim as new,and desire tosecure by Letters Patent of the United States, is'.

1. A resilient handle-bar for bicycles or the like, comprising ahandle-bar, sleeves 6 rigidly secured in the ends of said bar,rectangular longitudinal openings in said sleeves, fiat steel springsslidingly inserted therein, and set-screws inserted into the ends ofsaid bar and the sleeves in the same for adjusting the length of theactive part of the spring.

2. A resilient handle-bar for bicycles or the like, comprising ahandle-bar, sleeves b rigidly secured in the ends of said bar,rectangular longitudinal'openings in said sleeves, flat steel springsslidingly inserted therein, and set-screws inserted into the ends of thesaid bar and the sleeves in the same for adjusting the length of theactive part of the spring,.

and handles secured on the outer end of the springs, being provided witha tubular projection to fit over the free end of the handlebar and toform a rigid connection therewith.

Intestimony whereof I affix my signature.

MARTIN THIERFELDER.
